Half-pitch Low-profile Stacking Connectors

XH4A

An Integrated Male/ Female Half-pitch Stacking Connector with Board Space Adjustable from 5 to 11 mm.

*

■ Board space can be adjusted from 5 to 11 mm in

1-mm increments. (Surface-mounted Connectors can be adjusted from 5 to 9 mm in 1-mm increments.) ■ The product line includes DIP and SMT Connectors. ■ Integrated male/female Connectors. ■ All models incorporate fastening pins to secure

the terminals, thus preventing floating or falling over during soldering. ■ The leaf contact construction resists bending.

* Excluding SMT connectors

■ The XH4A conforms to UL standards (file no.

E103202). (SMT Connectors not included) ■ Not mated with XH2 and XH3 Half-pitch Connec-

tors. RoHS Compliant

■ Terminology • SMT The abbreviation of Surface Mount Technology. • Integrated male/female Connectors The male (plug) and female (socket) have the same shape.

• The triangular mark (▼) and contact num-

• On the mating side, the row of terminals on the raised reference point side are called row a, and the row on the other side is called row b. The numbers are in the order shown.

• XH4A Half-pitch Connectors are integrated male/female connectors. The contact numbers on row a correspond to the contact numbers on row b. Be careful when using these connectors because they function slightly differently from separate male and female connectors (i.e., Plugs and Sockets).

■ Precautions

Mating Compatibility

Be sure to wash the board after automated soldering is completed.

Correct Use

XH4 Half-pitch Connectors do not mate with XH2 or XH3 Half-pitch Connectors.

Soldering Conditions

XH4A Half-pitch Connectors are male/ female connectors with integrated plugs and sockets.

Straight DIP Terminals (Automated Soldering)

Refer to Contact Numbers above when designing boards.

(2) Continuous soldering time: Within 5±1 s

bers are not printed on the connectors. Use the raised reference point used to prevent reverse insertion as a guide when designing boards.

(1) Soldering temperature: 250±5°C

Recommended reflow conditions Pre-heat temperature: 150±10°C Pre-heat time: 60 to 120 s Soldering temperature: 200 to 240°C Soldering time: Within 30 s (Within 10 s at the maximum temperature of 240°C)
